¿Qué determina si un péptido es drug o biologic?

Principalmente el método de sintesis: peptidos sintetizados quimicamente son típicamente drugs (NDA/CDER), mientras que peptidos producidos por recombinant DNA son biologics (BLA/CBER). Tamaño, complejidad y precedent también influyen. Pre-IND meeting confirma clasificación.

¿Qué es un Complete Response Letter (CRL)?

Es comunicación de FDA indicando que application no puede ser approved en su forma actual. Identifica deficiencies en CMC, clinical, o nonclinical. Especifica qué se necesita para approval. El sponsor puede responder, apelar, o abandonar.

¿Cuál es la diferencia entre Priority y Standard Review?

Priority Review es 6 meses para drugs que ofrecen significant improvement sobre existing therapy. Standard Review es 10 meses. La designación se basa en therapeutic advance y unmet need. Priority no significa approval guaranteed.

¿Qué es un Pre-IND meeting?

Reunion formal con FDA para discutir development plan antes de IND submission. Topics incluyen toxicology design, clinical trial approach, manufacturing strategy y regulatory pathway. Requiere briefing document y questions específicas. Minutes pueden ser binding.

Vía Regulatoria para Péptidos Terapéuticos: FDA

Categorías: Metodología de Investigación, Control de Calidad, Información General

La vía regulatoria para peptidos en Estados Unidos sigue los pathways establecidos por FDA para biológicos o fármacos según su naturaleza. El understanding de los requirements, timelines y opciones de aceleración es esencial para planificación estratégica.

Resumen Simplificado

Los peptidos pueden ser drug o biologic según FDA. El pathway incluye IND → clinical trials → NDA/BLA. Expedited programs aceleran approval.
